Quick Start

Write and run your first Tenet program in 5 minutes.

The REPL

Start the interactive interpreter:

.\tenet

Try some expressions:

Tenet v0.1.0
>>> 2 + 2
4
>>> "Hello, " + "World!"
Hello, World!
>>> 10 > 5
true

Variables

var x = 10;
var name = "Alice";
var isPlaying = true;

print x;        // 10
print name;     // Alice
print isPlaying; // true

Functions

fun greet(name) {
    print "Hello, " + name + "!";
}

greet("Bob");  // Hello, Bob!

Functions can return values:

fun add(a, b) {
    return a + b;
}

var sum = add(3, 4);
print sum;  // 7

Control Flow

var score = 85;

if (score >= 90) {
    print "A";
} else if (score >= 80) {
    print "B";
} else {
    print "C";
}
// Output: B

Loops:

for (var i = 0; i < 5; i = i + 1) {
    print i;
}
// Output: 0, 1, 2, 3, 4

Your First Game

This is what Tenet was built for:

game RockPaperScissors {
    players Player1, Player2
    strategies Rock, Paper, Scissors
    
    payoff Player1 {
        (Rock, Rock): 0
        (Rock, Paper): -1
        (Rock, Scissors): 1
        (Paper, Rock): 1
        (Paper, Paper): 0
        (Paper, Scissors): -1
        (Scissors, Rock): -1
        (Scissors, Paper): 1
        (Scissors, Scissors): 0
    }
    
    payoff Player2 {
        (Rock, Rock): 0
        (Paper, Rock): -1
        (Scissors, Rock): 1
        (Rock, Paper): 1
        (Paper, Paper): 0
        (Scissors, Paper): -1
        (Rock, Scissors): -1
        (Paper, Scissors): 1
        (Scissors, Scissors): 0
    }
}

solve RockPaperScissors;

Save this as rps.tenet and run:

.\tenet rps.tenet
